Get PDFResearch aimed to measure the chemical compound in oil palm stem (Elaeis guinensis Jacq) based on height (base, middle, top) and depth (side, medium and core). Chemical properties studied are hot water soluble extractives content, solubility in 1% NaOH, benzene-soluble alcohol, holocellulosa, alpha - cellulose and lignin content. The procedure based on ASTM D 1110 – 56. Result of research showed that the average value of the levels of extractive substances in hot water ranged from 11,963% -15.032%, the average value of extractive substances soluble in 1% NaOH was range from 16.639% -18.027% and the average value of the levels extractive soluble substances of alcohol benzene ranged from 8.552% -10.693%. Meanwhile the average of holocellulose levels ranged from 82.534% -88.328% and the average value of alpha cellulose content ranged from 11.243% -68.761%. The average value of the lignin content ranges between 6.213% -33.702%. Analysis of variance showed that height and depth of stem was not significance to the levels of extractive substances in hot water, extractive substances soluble in 1% NaOH, extractive soluble substances of alcohol benzene, and holocellulose content. Meanwhile for alpha cellulose was significant. The height of stem was highly significant effect to lignin content, meanwhile depth of stem was not significant. This result showed that stem of oil palm can be used for composite board, particle board and other wood product. Keywords: Oil palm stem, extractives, lignin, cellulose, stem height, stem dept

Get PDFDevelopment of botanical gardens as a government effort to maintain the natural resource ecosystems may be affected by changes in the condition and development of social behavior in the surrounding communities. The purpose of this study was to determine the public's perception of community Sabung village towards development botanical garden in Sambas district. Data were collected by survey method by interviewing people in two villages located in the village Sabung. Respondents were selected by purposive sampling. the community is more than 3 years residing in the village Sabung. The results showed that there are differences in the perception of the botanical garden development. The public has a positive perception, and being negative about the development of botanical gardens Sambas district. However, the overall development of society agrees with Sambas district botanical gardens and take positive impact on the forest and surrounding communities. This difference in perception may be due to differences in the level of knowledge and lack of socialization by took instance on the development and benefits of botanical gardens.

Get PDFThe research aims to determine the physical properties (moisture content, density and dimensional stability) and mechanical properties (modulus of elasticity, modulus of rupture, and modulus of crush stiffness) of Elaeis guineensis Jacq based on the position the trunk). The design used in the study was a completely randomized design (CRD) with 3 replications and the factor is the position of the stem height (low, middle, and top) of oil palm (Elaeis guineesis Jacq). The results showed that height position have significant value to moisture content, MOR and MCS, but did not significantly affect the value of density, dimensional stability and MOE. The moisture content value was range from 38,49 % - 101,07 %, and the density value was range from 0,46 gr/cm3 – 0,62 gr/cm3, meanwhile the dimensional stability value was range from 11,54 % - 19,84 %. The modulus of elasticity value was range from 4456,77 gr/cm2 – 10062,40 gr/cm2, and modulus of rupture value was range from 108,20 gr/cm2 – 354,47 gr/cm2, meanwhile the modulus of crush stiffness value was range from 16,56 gr/cm2 – 69,96 gr/cm2. The research concluded that oil palm trunk in the low position have physical and mechanical properties better than in the middle and top, and enroll in class V of strongness and suitable for use as raw material for particle board or other composite products.

Kalimantan Satya Kencana is one of the forest where located in the Melawi district that has high enough of flora diversity. The medicinal plants that is part of the biological germplasm. The purpose of this study this to determine the diversity of medicinal plants in secondary forest (slash ex 2008) at the area of IUPHHK PT. Kalimantan Satya Kencana Melawi District. This study used quadrant method with multiple plots. Purposive sampling it has chosen by observation in according to the local communities most numerous types of medical plants. There was 71 medicinal plants outside the plots founded in the observations. The dominance index (C) of the tree level = 0.108. Tree level (C) of = 0.238. Saplings (C) of = 0.83. Plant Nursery and Lower level (C) of = 0.042. Species Diversity Index (H) to the level of the tree = 1.017, for the level of the pole (H) at = 0.629, sapling level (H) at = 1.084 and lower levels, and Plant Nursery (H) at = 1.455. Wealth index type (d) at tree level of = 6.695. Pole at = 2.590 level. Of = 10,204 saplings, seedlings and undergrowth for 20,325. Abundance index type (e) at the tree level of = 0.937. Tree level index (e) of = 0.924. Saplings (e) = 0.968 for seedlings and understory plants (e) of = 0.887. can be seen that the dominance index (C) which is highest at the Stake level, the value of Species Diversity Index (H) Rate of Seedling and Understory Plants and Index Property Type (d) which is highest at the level of the Seedling and Understory Plants, while the highest for the Abundance Index type (e) find at tree level.

The method used is survey method with descriptive associative and used interview techniques with instrument a questionnaire. There are two types of data analysis namely descriptive analysis used to see the general description characteristic of respondents and the level of public awareness and inferential analysis used to know different levels of income people who worked as fishermen and does not worked as fishermen by using independent sample t-test and to know the factors that affect the level of public awareness by using multiple linear regression models. The level of public awareness coastal in preserving function mangrove forest and brackish forest is tend high. The results of independent sample t-test indicated there was no significant difference between the average income levels of people who worked as fishermen with an average income levels of people who does not worked as fishermen. Based on the analysis used multiple linear regression models was knowledge variables and cosmopolitan variables significantly influence the level of public awareness, while age variables, income variables, and perceptons variable were not significantly influence the level of public awareness.
